Are you using the custom blur method ?

Are you using the custom blur method ?

Yes.

应该是StartAllBack导致的，我是AMD 5800X CPU，安装StartAllBack后，CPU温度70度，卸载后只有40度。

[teknixstuff]

I don't have startallback installed, that was a typo. I use StartIsBack++ currently.

Are you using integrated graphics + dynamic wallpaper?

[teknixstuff]

I have intergrated+dedicated graphics, and I don't have a dynamic wallpaper installed currently.

Make sure your dwm.exe is running on a discrete graphics card, in the test 5 windows in a frequently moving state the UHD 630 core graphics card had a resource usage of around 60%, while the RTX 3060 graphics card only had a resource usage of around 15% on 15+ windows.

Gaussian Blur is a GPU-intensive operation, which can lead to higher resource usage if your background is frequently updated or if you keep moving windows around.

if only windows would actually let me do that

How can I make sure it using dedicated GPU other than adding Graphic Settings on windows settings? Because it doesnt want to use my dedicated GPU for some reason.

一样的问题，仅开机位于桌面的情况下，打开dwmblurglass待机时gpu就占用60%，关闭后5%以下；
配置: Radeon 520 + i7-10700 + win11 23H2

Same issue here: when the computer is just started and on the desktop, opening dwmblurglass causes the GPU usage to reach 60% while idle; when closed, it drops to below 5%.
System configuration: Radeon 520 + i7-10700 + win11 23H2
